Abstract
ABSTRACTThe purpose of the research was to investigate the biosorption of Pb(II) by SVS (SVS, Cipangopaludina chinensis) using a batch technique. The kinetic behaviour was described better by pseudo-second-order model. The experimental isotherms obtained were fit better with Langmuir model, and according to the Langmuir equation, the maximum uptake capacity for Pb(II) was 333.3 mg g−1. Thermodynamic parameters and were calculated using the Van’t Hoff equation, and the results showed that Pb(II) sorption by SVS was an endothermic and spontaneous process. Results showed that SVS was a cost-effective biosorbent for Pb(II) biosorption.
